GLASS-MOLD.

Specification of Letters Patent.

Patented April 16, 1907.

Application tiled February 27,1907. Serial No. 359,567.

To all whom it may concern:

Re it known that I, STEPHEN HIPKINS, a citizen of the United States of America,` and a resident of Martins Ferry, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Glass- Molds, of which the following is a specification.

This invention relates to new and useful improvements in glass-molds, and more particularly to a mold wherein the stems and feet of blown-glass vessels are cast to the bodies or bowl portions ofsaid vessels.

The chief object of the invention is to provide a mold wherein stems and feet for glass vessels are simultaneously formed and cast to the bowls or body portions of said vessels.

A further object is to provide a device of the character mentioned wherein averticallyadjustable foot-forming plunger is provided, said plunger lraving a removable head which adapts it for the application thereto of other heads of different size or shape.

A still further object is to provide a mold of the character mentioned wherein removable andy interchangeable guide heads are employed which admit of the application thereto of interchangeable plungers for the formation. of glass feet of varying sizes.

l/Vith these and other objects in view the invention finally consists in the particular construction, arrangement, and combination of parts which will hereinafter be fully described, reference being herein had to the accomp anying drawings, forming a part of this specification, in which- Figure 1 is a vertical section of the invention. Fig. 2 is a side elevation of the lower portion thereof. Fig. 3 is a top plan view of the plunger-support, and Fig. 4 is a crosssection of the same.

Referring to said drawings, in which like reference numerals designate like parts throughout the several views, 1 indicates a centrally-apertured circular base having legs 2, and rigidly mounted upon said base is a centrally apertured top plate 3, having a shouldered annular recess 4, in which is fitted and secured by means of screws 5 the ange extension 6 of a detachableguide-head 7.

Mounted upon the top plate 3 of the lower portion of the mold is the upper portion 8 of said mold, said upper portion consisting of two or more parts hinged together, as at 9. In said upper portion 8 is a vertical central leg-aperture 10, which terminates at its lower end in a. iiared foot-recess 11. In said upper portion below said foot-recess is formed a fianged recess 12, in which fits the flange 13 of the guide-head 7 thus securing the bottom portion of the mold to the upper portion thereof when the latter is closed. Said upper portion consists, further, of a removable plate 14, composed of a number of' sections corresponding to the number of sections of thepart 8, which plate surmounts part 8, being secured thereto by screws 15. Said plate 14 has a central aperture therein for the reception of the lower part of the blown bowl 16, the walls 17 defining said aperture being shaped to form a seat for said bowl. An integral apertured head 18, carried by said plate 14, forms a part of said seat, said head prefer` ably having an internal annular recess 19, lled with asbestos 20 for contacting with the bowl to prevent the cracking of the latter, which would be liable to occur were a whole metal seat employed The plate 14 being readily removable,it will be seen that by employing interchangeable plates bowls of widely-varying sizes may be mounted on the mold.

Provided in the outer upper edge of the base 1 is an annular recess 21, which together with the overhanging rim of the top plate 3 forms an annular groove in which is movably held or supported the inturned flange 22 of an apron 23. Said apron has a handle 24, by means of which it may be partially revolved and is formed with inclined slots 25 at regular intervals. Inclosed by said apron is a vertically-movable disk 26, having an annular downturned flange 27 and provided with re-` cesses 2S therein in which fit the legs 2. Said disk is supported by pins or bolts 29, mount ed in holes 30 in said ilange 28 and projected outward through the inclined slots 25 of the apron, said pins or bolts preferably having antifriction -rollers 43 thereon. Said disk has a central threaded aperture therein in register with the central aperture of the base 1, and extended through said apertures is the body portion of a cylindrical plunger 31, having an adjustable and removable bead 32. The lower portion of the bodv portion of said plunger 31 is eXteriorly threaded, as sb. own at 33, and is in threaded engagement with said disk 26, being thus vertically adjustable with TOO relation to said disk. Said plunger has a being readily grasped by a wrench for rotating. A nut 35, threaded upon the plunger, serves to lock said plunger in adjusted position with relation to said disk.

The head 32 of the plunger, whose upper face may be of any preferred form adapted for shaping the foot 36 of the glass article, has a central stem 37 on its lower end adapted for fitting within a socket 38 in the upper end of the body portion, and extending upwardj through a central bore 39 in said body portion and threaded into a socket 40 in the stem 37 ofthe head 32 is a bolt 41. As is'obvious, by manipulating said bolt said head may be adjusted slightly with relation to said body portion of the plunger. A dowel-pin 42, having its opposite ends fitted in sockets respectively provided in said head and said body portion, serves to prevent rotation of said head with respect to said body portion.

In operation the bowl 16 is placed in the seat provided therefor in the upper portion of the mold for casting a leg thereto or thereupon, a sufficient quantity of molten glass for said leg and its foot 36 having previously been placed in the mold upon the plunger- Then the j head 32 and the mold closed. plunger having been previously lowered to substantially the level of the top of the guide-head 7 is raised by revolving the apron 23, which is vertically immovable, the pins or bolts 29, supporting the disk 26, being moved upward in the inclined slots 25. l/Vith the raising of the plunger the molten glass is forced up into the leg-aperture 10 and the foot-recess 11 and is therein cast in its proper shape and at the same time is made to adhere to the bowl 16. It will be noted Vthat the formation of the foot-recess l1 is such that the foot 36 cast therein is substantially cup-shaped. When removed from the mold, said foot is flared or opened outward in a manner well understood.

The head 32 of the plunger is readily adjusted with relation to the guide-head 7 by means of the bolt 41 to regulate the thickness of the foot 36. Said head 32 being removable, provision is thereby made whereby a variety of formations of said head may be employed in connection with the mold for forming feet of varying shapes, and the guidehead being removable provision is made whereby plunger-heads of varying sizes may be employed.

It will be noted that the mold is so constructed that'it is adapted for casting legs upon articles of ware having bowls of varying sizes and shapes, many of its parts being adjustable and interchangeable.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
